One thing that I've noticed over the past few hours is VEHICLE TYPE!!! What works well on a Toyota Camry probably will NOT work well on my '82Trans Am. Weight balance of a vehicle is VERY important. Firebird's,Camaro's and Mustang's have, historically, been notorious for being rear-end light, hence no winter traction to speak of. I've personally run Goodyear ST's, Pirelli P400's, and Dunlop D60A2's on my T/A. The Pirelli'swere, far and above, the better tires. I just can't FIND them any longer.
